HDMI Loses Audio
Hi. I've done some poking around and while I found some threads with HDMI audio issues, none seemed exactly like what I'm experiencing, so I wanted to ask for some help.
My system is a: MythTV Box running 12.04 / .25myth. It's connected to an HDMI receiver that then transmits both audio and video to a 47" 1080p tv.
On bootup and while watching tv, all works normally - correct resolution, sound & video working properly.
- In the event that the receiver is turned off, turning receiver back on results in video but no audio
- On occassion, screen resolution will change from 1080 to 720. With this change, all audio via HDMI turns off. This happens not while watching videos, but rather when I drop to the main interface (XFCE) and interact with other applications (browser, etc...). Seems random.
For what it's worth, neither of these were issues pre-upgrade to 12.04.
My guess is that somehow the HDMI connection gets randomly tweaked due to delays, etc.... A simple logout / login fixes the problem, but this is annoying if recording activity is underway.
Have any others experienced a similar issue / have a work-around?
Alternately, does anyone have a command line hack to effectively reset the HDMI connection? (yeah... colloquial)
Thanks for any help.

Reason: overstated tv size
